Migrate SiStripGainsPCLWorker to concurrent and global DQM

[mmusich]

Greetings,
I am re-proposing #22320 with a clean git history this time, and some further cleaning.
The purpose of ec655a6 remains the same, moving the "worker" step of the SiStrip gains PCL workflow to concurrent and global DQM.
The advantage in terms of memory consumption, after the migration to edm::one of the DQMEDAnalyzer, of running step3 of runTheMatrix.py -l 1001.0 -t 4 is reduced, but still visible.

The other advantage I can see is that if running (in standalone mode) the Gain Calibration in a plain CMSSW_10_1_0_pre2 (in single-threaded mode) via:

cmsDriver.py step3 --datatier ALCARECO --conditions auto:run2_data -s ALCA:PromptCalibProdSiStripGains --eventcontent ALCARECO -n 100 --dasquery='file dataset=/ZeroBias/Run2016C-SiStripCalMinBias-18Apr2017-v1/ALCARECO run=276097'

followed by:

cmsDriver.py stepHarvest --data --conditions auto:run2_data --scenario pp -s ALCAHARVEST:SiStripGains --filein file:PromptCalibProdSiStripGains.root -n 100 --fileout file:calib.root

one receives a segmentation fault (stack is available here ), while this PR changes this is not the case.
Running the step3 in MT mode even in CMSSW_10_1_0_pre2 with:

cmsDriver.py step3 --datatier ALCARECO --conditions auto:run2_data -s ALCA:PromptCalibProdSiStripGains --eventcontent ALCARECO -n 100 --dasquery='file dataset=/ZeroBias/Run2016C-SiStripCalMinBias-18Apr2017-v1/ALCARECO run=276097' --nThreads 4

doesn't produce a segfault.
I profit of this PR to update the unit test with the standalone harvester step to be run in sequence after the Analyzer step in 5fa99ec.
As a final note to the reviewers no algorithmic change is intended by this PR, so both calibration output and monitoring plots shall remain the same. This is validated cross-checking the outputs of running the workflow on 1000 events of run 276097 here.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
